The Structure of Spellcasting

Both for beginners to magic and to those who wish to fine-tune their craft. What makes a spell work? What impedes its progress? What are the preconditions for a spell to succeed? How do the magician, the target, the goal, and the Gods affect a spell? Magic is an integral part of many of our lives, yet much of the magic we do is left unanalyzed. By looking closely at what does and doesn't work, we can improve our spells.
